DONUT-SHAPED AQUACULTURE TANK FOR INCUBATION OF EEL

摘要

The present invention provides an incubation system for fish larva which automatically mixes a liquid feed in an aquaculture tank at a proper flow rate to increase the survival rate of early-stage larval eels and to manage the early-stage larval eels in large amounts. The circulation rate and location of water is adjusted to exact figures which do not impose stress on the early-stage larval eels for an increased survival rate and mass production of the early-stage larval eels.
